[cumbria_lug] Dynamic Updates in BIND 9 Serving XP and 2003 Server

[Malcolm Logan]

Tevor,

Thanks for your email. I have turned off SELinux and unfortunately has
made no difference.

I'm wondering if I've understood the Dynamic Updates feature of BIND9
correctly. My understanding is that as long as I allow these in the
named.conf file per zone with 'allow-update' (in conjunction with the
appropriate IP address based ACL) then when I instruct an XP client to
use the BIND9 server as its primary DNS server then the XP client should
register its own IP address and a some_zone.jnl should be created in the
named directory.

I'm pretty certain I've got that right but I may be mistaken?

M

Malcolm,

I don't have enough time this week to figure out what problem your 
having but I guess there are one or two places you might look firstly 
there is the Linux Documentation Project Network Admin Guide at ----

http://www.tldp.org/LDP/nag2/index.html
http://www.tldp.org/LDP/nag2/x-087-2-resolv.html

Also It might be a conflict between your setup and recent changes to the

Fedora distro (3 + 4) some difficulties with system deamons are due to 
having 'SELinux' running in 'Secure policy' mode try looking under 
'System Settings' 'security level' and if SELinux is enabled check that 
you are using 'targeted' and not 'secure' policy then there is a 'Name 
Service' section try ticking the 'allow' boxes as the default is to 
not-allow such things as writing to the Master Zone file (It uses the 
term 'overwrite' which could well be the cause of your trouble.. If your

still having trouble try turning SELinux off.

Do let us know if any of this is helpful or if you have tried any of 
these things
